CHARLES R. OSBORNF., OF DANBURY, CONNECTICUT.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,791, dated May 13, 1890.

Application filed September 5, 1888. Serial No. 284,612. (No model.)

To @ZZ whom zit may concern:

Be 1t known that I, CHARLES R. OsBoRNE, a citlzen of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented cert-ain new and useful Improvements in Type-Iriting Ma chines; and I do hereby7 declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in type writing machines, and has for its object to provide such a device which shall be simple of construction and easy of manipulation.

Vith these ends in View my invention consists in the details of construction and combination of elements hereinafter set forth, and then specifically designated by the claims.

In order that those skilled in the art to which myinvention appertains may understand how to make and use the same, I will proceed to describe its construction and operation in detail, referring by letter to the accompanying drawings, forming a part of this speciiication, in which" Figure 1 is a plan View of my improvement; Figi 2, a central vertical section thereof, the paper carriage and roll being left in eleva tion; Fig. 3, a plan View of the paper-carriage, roll, and its operating mechanism. IFigs. 4c and 5 are details of the clamp for securing paper upon the roll; and Figs. 6, 7, and S, diagrams illustrating' the several positions of the type and type-operating mechanisms.

Similar letters denote like parts in all the iigures of the drawings.

A is the base-plate, of such shape as to aceommodate the operating parts of the machine, and B are standards projecting upward therefrom. To these standards Vat a is pivoted what I call the crown A, its forward portion being supported bya bracket C, formed with the bed-plate, so that it will be seen that said crown may be swung up ward and backward, for the purpose hereinafter explained.

Dare key-levers, pivoted at b within the crown, and to the outer ends of these levers are pivoted the type-bars E, which project through the slots F, formed in the inner slots L, formed in the inner wall of the crown,

for the purpose to be hereinafter explainedf and M are coil-springs attached to said pins and crown for retaining the keys in their normal elevated position, as shown in Figs. 2 and G.

The keys I as will be seen by reference to Figs. l and 2, are arranged in a higher plane and smaller are than the keys I, and the upper portions of their stems J are bent, in order that the lower portions may enter the crown in the same arc as the stems J.

The operation of the type-actuating mechanism as thus far deseribedwill be as follows: Sufficient pressure being brought to bear upon a key to overcome the action of the spring M, the lever D will be depressed from the position shown in Fig. G to that shown in Fig. 7, thereby projecting the type-bar outward, and as the upper edge of the latter bears against the upper wall of the slot F by reason of the action of the coil-sprin g d said bar will be guided so that its type G will take thc position clearly indicated in Fig. 7. Uien it is desired to imprint the characterof the type upon the paper, (denoted by theli11ee,)itiso11ly necessary to force the bar downward against theresilien ey of its spring d, which latter operation will be next explained. The pressure on the key being released, the spring M will return the type-bar and its connections to their normal position, with the type bearing upon ,f

the inking-pad li', thereby replenishing said type with ink.

N is a semicircular frame, the upper edge of which in its normal position lies under the pins K and within their field of action. The rear ends of this frame extend backward and are pivoted at f to the crown near the fulcrum of the latter.

O is a hammer formed with and projecting downward from the frame N, and P is a coil" IOO spring, the ends of which are secured to the crown and said frame, so as to keep the latter in its normal position against the stop-pins g.

Now it will be obvious that as a key is depressed to bring the type-bar to the position shown in Fig. 7 the pin carried by said key in its downward course will strike against the upper edge of the frame N, when said frame and pin will move in unison until the latter vis arrested by the bottom wall of the slot L; but the frame, having acquired sufficient momentum,will continue its movement from the position shown in Fig. 7 to that shown in Fig. 8. whereby the hammer is caused to force the type against the paper and effect the imprint of the character. l/Vhen the inertia of the frame is thus overcome, the spring P will quickly return it to its normal position.

It will be understood that as the type-bars are arranged and guided radially from a point which coincides with the vertical plane of the hammer said hammer will operate either of said bars when in their projected position, and as the hammer-frame is in the field of operation'of all the key-pins said hammer will be caused to operate by the depression of any of the keys, as above described.

Q is the paper-roll mounted on the shaft R, journaled within the carriage S, which latter is supported by and adapted to travel upon the rods or tracks T T', rolls h 'L' serving to reduce the friction between said carriage and tracks. These tracks T T are supportedby posts U U', respectively, which project from the bed-plate.

To the front edge of the carriage is secured a rack-bar V, and 7c is a pawl adapted to cngage the teeth of said bar to intermittently propel the carriage, for the purpose presently explained. The pawl 7c is carried by the inner end of the hand-leverVV, which is pivoted at Z to the bracket C and terminates at its outer end in a button m in convenient reach of the operator.

.X is a post formed at one side of the carriage, to which is pivoted a pawl-lever Y, carrying at one end the pawl n, adapted to engage theratchet Z, which latter is secured to the paper-roll Q. The coil-spring o serves to return said lever and pawl to their normal position.

p are clamps hinged between ears q at the outer edge of the paper-roll in such manner as to operate after the order of a clasp-knife. These clamps are for the purpose of holding the paper to be written upon around the roll, as clearly shown in Fig. 3. To secure the I paper upon the roll, it is only necessary to pass it around said roll and close the clamps upon it.

In my improvement the lines of writing run aroundthe roll, and the spacing between said lines is lengthwise of said roll and accomplished through the hand-lever W and pawl 7c actuating the carriage longitudinally. Therefore it is obvious that after the depression of each key to imprint a character it is only necessary to move the roll one step on its axis in order to produce the proper spacing between said character and the one next to be imprinted. This I effect as follows: A' is a striker depending from the rod B', which latter is secured to the hammer-frame. This striker hangs in a vertical plane immediately over the forward portion of the pawl-lever Y, and is extended sufficiently to operate upon the lever throughout the longitudinal movement of the latter, so that it will be seen that at every downward stroke of the hammer the striker will depress the lever Y against the resiliency of the spring o, thus causing the pawl n to engage a new tooth of the ratchet, and as the striker is elevated by the upward movement of the hammer-frame the spring 0 will actuate said pawl to revolve the paperroll one step. Vthen one line has been completed, to start the next it is only necessary to operate the hand-lever W in the direction of the arrow, which, as before described, will cause the carriage to advance a proper distance to form the space between the lines, the spring r returning said lever to its normal position. The track T may be roughened or notched, in order to prevent any overthrow of the carriage when actuated by the handlever. To effect the spacing between words and at other times when required, I provide keys C', supported on spindles D', projecting upward from the hammer-frame, and it will be obvious that by depressing either of these keys the striker will be caused to operate the pawl-lever Y, thus revolving the paper-roll,

as before described in connection with thel spacing of the characters.

If at any time it becomes desirable to revolve the roll through a considerable arc, it may be accomplished without resort to the spacing-keys by manipulating either of the thumb-wheels E. To place the paper upon the roll, the crown is turned back upon its pivots until the stops s, striking the standards, prevent further movement, thus permitting free access to said roll, and to further facilitate this operation the carriage and roll itself may be swung around the rod T, and said carriage is prevented from leaving said rod by bracket-hooks F', partially encircling the latter.

In writing bills and the like,where it is nec essary to frequently skip a considerable distance, as in moving the paper from one column to another, it is especially advantageous to produce such movement independently, and said movement may be so effected by the mechanism which I will now describe, and which is shown in Figs. 2 and 3.

Secured to the shaft R of the paper-roll is a small ratchet-wheel F, with which engages a ratchet-bar G. One end of this bar is pivoted to a swinging frame H', which `extends the entire length of the carriage and is swung from a rod K', supported by said carriage.

L is a bell-crank lever pivoted to the lug t,

its Vertical arm bearing against the frame I-I and its longitudinal arm extending within the eld of action of a hand-lever M', which latter is pivoted to the bracketC and has its forward end within easy reach of the operator.

By depressing the hand-lever M the bellcrank lever will throw the frame in the direction of the arrow, thereby causing the ratchet-bar to revolve the paper-roll through an arc proportional to the movement ot' said hand-lever, which movement may be regulated and adjusted by the thumb-screw N. A coil-spring o serves to hold the bar G in engagement with the ratchet-wheel, and also to return said bar and the frame to their normal position.

Having thus fully described my invention, what I claim as new and useful is l. In combina-tion, the inking-pad, the typebars E, the type carried thereby, held normally in Contact with said pad, the guides F, the key-levers I), pivoted to said type-bars, and the keys attached to said levers, whereby downward pressure thereon will project the type into position under the hammer, as set forth.

2. In combination,theinkingpad, the typebars TE, the type carried thereby, held normally in contact with said pad, the key-levers D, pivoted to said type-bars, the keys attached to said levers, whereby downward pressure thereon will project the type into position under the hammer, and the pivoted hammer-frame n nder control of said keys and carrying the hammer O, as set forth.

3. In a type-writing machine, the combination of the radiating bars carrying type at their inner ends, keys for projecting said type to a common center under a hammer, astriking-pin carried by each key, a hammerframe in the line of operation of all the strikingpins, a hammer carried by said frame at the common center of the bars, and a striker attached to said frame and engaging` and operating the character-spacing mechanism, as set forth.

4. In combination, the paper roll, the ratchet and pawl Z 0L, the semicircular hammer-frame pivoted at f, the striker A', carried thereby, the hammer O, the type-bars radiating from a point under said hammer, and the keys and key-levers for operating all these parts consecutively, as set forth.

5. In combination, the radiating type-bars carrying type, the arc-shaped ink-pad,with which said type are normally held in contact, the semicircular ham mer-framecarryin g hammer O overthe center of radiation of the typebars, the keys and key-levers radially arranged and connected to the type-bars, and the radially-arranged striking-pins connected with the 'key-levers and projecting over the hammer-frame, as and for the purpose set forth.

G. The combination of the keys, key-levers, and type-bars, hammer-frame under control of said keys, striker carried by said frame, the lever Y and its operating-pawl, the ratchet actuated by said pawl, the paper-roll carrying said ratchet, the carriage on which the roll is mounted, tracks upon which the carriage is adapted to travel, a ratchet-bar secured to the front of said carriage, and a hand-lever and pawl, whereby said ratchetbar is actuated to propel the carriage longitudinally, substantially as and for the purposes herein set forth.

In testimony whereof I affix my signature in presence ot' two witnesses.

CHARLES R. OSBORNE.
